Data

Sheet

The sector erase architecture allows memory sectors to be erased and reprogrammed

without affecting the data contents of other sectors. The device is fully erased when

shipped from the factory.

Hardware data protection measures include a low VCC detector that automatically in-

hibits write operations during power transitions. The device also offers two types of data

protection at the sector level. The sector lock/unlock command sequence disables or

re-enables both program and erase operations in any sector. When at VIL, WP# locks

sectors 0 and 1 (bottom boot device) or sectors 132 and 133 (top boot device).

The device offers two power-saving features. When addresses have been stable for a

specified amount of time, the device enters the automatic sleep mode. The system can

also place the device into the standby mode. Power consumption is greatly reduced in

both modes.

Spansion flash technology combines years of flash memory manufacturing experience to

produce the highest levels of quality, reliability and cost effectiveness. The device electri-

cally erases all bits within a sector simultaneously via Fowler-Nordheim tunnelling. The

data is programmed using hot electron injection.
